Problems solved by technology

[0006] If a certain MME in the MME POOL fails, the MME will lose the context information of all users in the session with itself. Although other MMEs in the pool can continue to serve these users, these MMEs do not have the user context information, which will make the user’s If the data service is interrupted, the user must re-initiate the attachment process and attach to another MME before resuming the session
Due to the interruption of the user's data service during the period, the user experience will be very poor

Embodiment 1

[0038] see figure 2 , this embodiment provides a method for maintaining business continuity, including:

[0039] 101: When the first mobility management entity fails, acquire first identification information and second identification information, where the first identification information is identification information of a storage device, and the storage device is used to store the current status of the first mobility management entity. The first bearer context information of the session, the second identification information is the identification information of the user equipment in the connected state served by the first mobility management entity;

[0040] 102: Acquire, from the storage device corresponding to the first identification information, the first bearer context information of the current session corresponding to the user equipment according to the second identification information;

[0041] 103: Establish a bearer for the user equipment according to the first b...

Embodiment 2

[0089] see Figure 5 , this embodiment provides a system for maintaining service continuity, the system includes: a storage device 41 and a mobility management entity 42;

[0090]The storage device 41 is configured to back up the first bearer context information of the current session of the first mobility management entity, and receives the restore context request sent by the mobility management entity 42, the restore context request carrying the context information served by the first mobility management entity and send the first bearer context information corresponding to the identification information to the mobility management entity 42; the first bearer context information is corresponding to one or more user equipments in the connected state served by the MME The bearer context information of the current session.

[0091] The specific process of backing up the first bearer context information is as follows:

[0092] The storage device 41 receives the establishment (or...

Embodiment 3

[0099] see Figure 7 , this embodiment provides a mobility management entity 42, including: an identification information acquisition module 421, a context acquisition module 422, and a service continuity maintenance module 423; wherein,

[0100] The identification information acquiring module 421 is configured to acquire first identification information and second identification information when the first mobility management entity fails, the first identification information is identification information of a storage device, and the storage device is used to store the first identification information First bearer context information of a current session of a mobility management entity, where the second identification information is identification information of a user equipment in a connected state served by the first mobility management entity;

[0101] A context obtaining module 422, configured to obtain, from the storage device corresponding to the first identification inf...

Abstract

The invention discloses a method, a system, a mobility management entity and a memory device for maintaining service continuity, and belongs to the field of wireless communication. The method comprises the following steps of: acquiring first and second identification information when a first mobility management entity has a failure; acquiring first context carrying information of a present sessioncorresponding to user equipment from the memory device corresponding to the first identification information according to the second identification information; and establishing load bearing for theuser equipment according to the first context carrying information. The system comprises the memory device and the mobility management entity. The mobility management entity comprises an identification information acquisition module, a context acquisition module and a service continuity maintaining module. The memory device comprises a context backup module and a context transmission module. The method, the system, the mobility management entity and the memory device realize the uninterrupted effect of data service of a user when the mobility management entity has the failure, and greatly improve user experience.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a method, system, mobility management entity and storage device for maintaining service continuity. Background technique [0002] In order to adapt to the development of communication technologies, the 3GPP (3rd Generation Partnership Project, 3rd Generation Partnership Project) organization has formulated a wireless network evolution plan. The current wireless network evolution version is R8 version, that is, SAE (System Architecture Evolution, system architecture evolution). [0003] In order to maintain service continuity, SAE proposes a solution of MME POOL (Mobility Management Entity POOL, mobility management entity resource pool). The MME POOL is composed of multiple MMEs with the same function, and the UE (User Equipment, user equipment) does not need to replace the serving MME within the service area of ​​the MME POOL. MME POOL has the feature of maintaining busine...
